| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2009-09-18 | CVE-2009-3238 | Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) vulnerability in multiple products The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to "return the same value over and over again for long stretches of time." | 5.5 |
| 2009-08-27 | CVE-2009-2698 | NULL Pointer Dereference vulnerability in multiple products The udp_sendmsg function in the UDP implementation in (1) net/ipv4/udp.c and (2) net/ipv6/udp.c in the Linux kernel before 2.6.19 allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving the MSG_MORE flag and a UDP socket. | 7.8 |
| 2009-08-14 | CVE-2009-2692 | Use of Uninitialized Resource vulnerability in multiple products The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket. | 7.8 |
| 2009-06-08 | CVE-2009-1961 | Improper Locking vulnerability in multiple products The inode double locking code in fs/ocfs2/file.c in the Linux kernel 2.6.30 before 2.6.30-rc3, 2.6.27 before 2.6.27.24, 2.6.29 before 2.6.29.4, and possibly other versions down to 2.6.19 allows local users to cause a denial of service (prevention of file creation and removal) via a series of splice system calls that trigger a deadlock between the generic_file_splice_write, splice_from_pipe, and ocfs2_file_splice_write functions. | 4.7 |
| 2009-04-06 | CVE-2009-1243 | Improper Locking vulnerability in Linux Kernel net/ipv4/udp.c in the Linux kernel before 2.6.29.1 performs an unlocking step in certain incorrect circumstances, which allows local users to cause a denial of service (panic) by reading zero bytes from the /proc/net/udp file and unspecified other files, related to the "udp seq_file infrastructure." | 5.5 |
| 2008-09-29 | CVE-2008-4302 | Improper Locking vulnerability in multiple products fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a failure of the add_to_page_cache_lru function, and subsequently attempts to unlock a page that was not locked, which allows local users to cause a denial of service (kernel BUG and system crash), as demonstrated by the fio I/O tool. | 5.5 |
| 2008-09-04 | CVE-2007-6716 | fs/direct-io.c in the dio subsystem in the Linux kernel before 2.6.23 does not properly zero out the dio struct, which allows local users to cause a denial of service (OOPS), as demonstrated by a certain fio test. | 5.5 |
| 2008-05-08 | CVE-2008-1669 | Race Condition vulnerability in Linux Kernel Linux kernel before 2.6.25.2 does not apply a certain protection mechanism for fcntl functionality, which allows local users to (1) execute code in parallel or (2) exploit a race condition to obtain "re-ordered access to the descriptor table." | 6.9 |
| 2007-06-11 | CVE-2007-2876 | Denial Of Service vulnerability in Linux Kernel SCTP Connection The sctp_new function in (1) ip_conntrack_proto_sctp.c and (2) nf_conntrack_proto_sctp.c in Netfilter in Linux kernel 2.6 before 2.6.20.13, and 2.6.21.x before 2.6.21.4, allows remote attackers to cause a denial of service by causing certain invalid states that trigger a NULL pointer dereference. low complexity linux | 6.1 |
| 2007-06-11 | CVE-2007-2453 | Unspecified vulnerability in Linux Kernel The random number feature in Linux kernel 2.6 before 2.6.20.13, and 2.6.21.x before 2.6.21.4, (1) does not properly seed pools when there is no entropy, or (2) uses an incorrect cast when extracting entropy, which might cause the random number generator to provide the same values after reboots on systems without an entropy source. | 1.2 |
